It is found that a quartz crystal microbalance signal is proportional to the product of mass and intrinsic viscosity of molecules at solid–liquid interfaces, with a constant coefficient. This relationship provides a convenient way to semi-quantitatively probe the conformation of a discrete polymer at solid–liquid interfaces.
